MSMPR Crystallization equipment

By Chemical Engineering |

Crystallization is a key purification technique for various sectors of the chemical process industries (CPI). Several approaches for industrial crystallization have evolved over time and highly specialized crystallizer designs have been developed, especially in long-established industries. Solution crystallization is an important unit operation because the process can generate high-purity products from solutions containing significant levels of impurities with relatively low energy input. One scheme for classifying this equipment is according to the method used to suspend the growing crystals. In this scheme, a class of equipment known as mixed-suspension, mixed-product-removal (MSMPR) crystallizers is most important for the CPI. MSMPR Forced-circulation (evaporative) crystallizer Draft-tube-baffle (DTB) crystallizer Source for diagrams: Perry’s Chemical Engineers’Handbook, Swenson Process Equipment MSMPR crystallizers, also known as magma-circulation crystallizers, have found widespread application in the CPI for continuous crystallization. In this configuration, a feed solution is continuously introduced into the crystallizer, which is equipped with a mechanism…
